[0002] A connecting wall member generally refers to a member that strengthens the stability of other structures by connecting to a reliable fixed end. In construction projects, it is used to connect the scaffold frame of precast members to the main building structure and can transmit tensile and compressive forces. The attached wall connection achieved by using connecting wall members plays an important role in strengthening the overall stability of the scaffold, improving its stable load-bearing capacity, and avoiding major accidents such as tipping or collapse.

[0003] For example, Chinese Patent CN209011538U discloses a new type of connecting wall member device for a safe external frame, which relates to the technical field of building construction; it includes a pre-embedded component and a connecting component. The connecting component includes a steel bar screw, a connecting sleeve, a cross-shaped fastener, and a mountain-shaped clamp. The pre-embedded component is pre-embedded in the wall concrete and includes a pre-embedded steel bar body and a steel bar connecting sleeve. Compared with the prior art, it reduces the material waste caused by directly pre-embedding steel pipes and avoids the construction, installation, and demolition of secondary structure masonry, which is very convenient and fast, and effectively guarantees the construction quality of the connecting wall member and the safety of the safe external frame.

[0004] Although the above patent effectively guarantees the construction quality of the connecting wall member and the safety of the safe external frame, in this patent, a single steel bar connecting sleeve, connecting sleeve, and steel bar screw are used for setting, and its connection and fixation stability with the external frame is general, reducing the practicability. Content of the Utility Model

[0007] The strengthening mechanism includes a first threaded rod threadedly connected inside two embedded threaded cylinders. A first threaded connection cylinder is fixed to the right side of the first threaded rod. A second threaded rod is threadedly connected inside the first threaded connection cylinder. A strengthening solid connecting rod is fixed to the right side of the second threaded rod. Strengthening frames are slidably connected to the outer sides of the upper and lower strengthening solid connecting rods. A connection assembly is provided on the right side of the upper and lower strengthening solid connecting rods.

[0008] Furthermore, the connection assembly includes third threaded rods fixed to the right sides of the upper and lower strengthening solid connecting rods. A second threaded connection cylinder is threadedly connected to the outer side of the right side of the third threaded rod. An installation plate is fixed to the right side of the second threaded connection cylinder. The right sides of the upper and lower installation plates are fixed to the safety outer frame body by bolts.

[0009] Furthermore, fixing half rings are fixed to the upper and lower sides of the upper and lower first threaded connection cylinders. Fixing steel wires are fixed to the outer sides of the fixing half rings.

[0010] Furthermore, the embedded reinforcing bar is located on the longitudinal central axis of the embedded steel bar body.

[0011] Furthermore, the three reinforcing embedded rings are evenly distributed on the outer side of the embedded steel bar body.

[0012] Furthermore, the upper and lower embedded connecting steel bars are symmetrically distributed on the upper and lower sides of the transverse central axis of the embedded steel bar body.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] 1. For the outer frame connecting wall member device on the precast member, the two strengthening frames are inserted on the outer sides of the two strengthening solid connecting rods, penetrated by the first threaded rod on the left side, and then the two first threaded rods are threadedly connected inside the right sides of the upper and lower embedded threaded cylinders.

Then, the two installation plates are fixed to the left side of the safety outer frame body by bolts. The stability of the fixation can be improved by fixing the ends of the four fixing steel wires away from the four fixing half rings to the safety outer frame body where they can be fixed, thereby enhancing the stability of the connection and fixation.

[0015] 2. For the external frame connecting wall device on the precast component, when the upper and lower first threaded rods are removed from the internal of the upper and lower embedded threaded cylinders, rubber plugs can be used to plug the internal of the upper and lower embedded threaded cylinders. At the same time, after the external frame is used up, the upper and lower embedded threaded cylinders can be filled with concrete without removing the embedded steel bar body, which can improve the safety quality of the wall.
